This is a magnifying glass frame.
Designed for glass that has been rimless for a long time.
The package contains two stl files.
You need to print the frame file twice as it holds the glass on both sides, for which there
are corresponding grooves and then glue it.
You also need to print out the handle for the frame and glue it to the frame after you insert
the glass into it and glue it.
The size of the handle depends on the size of the frame, and the size of the frame
depends on the size of the glass.
Therefore, adjust the dimensions in the slicer yourself.
I hope I helped you in the way that I myself could not find for a long time and did not find,
as you understand, a 3d model of a frame for a magnifying glass, so I created it myself. :)
I will be glad if you support me.
All health and success!!!
